Spring Boot 集成 Socket.IO 是将实时通信功能融入到 Spring Boot 应用程序中的一种常见做法,通常用于构建WebSocket应用,如聊天系统、在线协作工具等。以下是一般的步骤:
1. 添加依赖:首先,在你的`pom.xml`或`build.gradle`文件中添加Socket.IO客户端库(例如`socket.io-client-java`)和相关的Spring WebFlux依赖。
```xml
<!-- Maven -->
<dependency>
<groupId>io.socket</groupId>
<artifactId>socket.io-client-java</artifactId>
<version>1.4.0</version>
</dependency>
<!-- Gradle (example) -->
implementation 'io.socket:socket.io-client-java:1.4.0'
```
2. 创建WebSocket服务:在Spring Boot应用中,创建一个WebSocketHandler,它会负责处理来自客户端的消息和连接管理。
```java
import io.socket.IOAcknowledge;
import io.socket.SocketIOClient;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;
@Component
public class SocketIoHandler {
@MessageMapping("/message")
@SendTo("/topic/messages")
public String handleMessage(String message, IOAcknowledge acknowledge) {
// ...处理消息逻辑...
return "Message received";
}
}
```
3. 启动WebSocket服务器:在Spring Boot配置类中启用WebSocket支持,并绑定Socket.IO服务到特定端口。
```java
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/socket.io").withSockJS();
}
}
```
4. 客户端连接:使用JavaScript的Socket.IO库连接到服务器提供的URL,比如`ws://localhost:8080/socket.io`,并开始发送和接收消息。
```javascript
var socket = io('ws://localhost:8080/socket.io');
socket.emit('message', 'Hello from client');
socket.on('message', function(data) {
console.log('Received:', data);
});
```
